SPRING TROLLEY EAR AND HANGER.

Application filed August 4, 1922. Serial No. 579,686.:

To all whom it may concern:

Be it known that 1, JAMES Soorr, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Spring Trolley Ears and Hangers, of which the following is a specification.

y invention relates to an improvement in a spring trolley ear and hanger, the object being to provide a durable resilient means of suspending a trolley wire from an overhead support especially at such points and places in the line of the trolley wire where conditions require a relatively low suspension, as underneath bridges where an augmented or heavy strain is imposed upon the suspension means by the operation of the trolley.

In the annexed drawing, Fig. 1 is a side view of my improved ear and hanger, showing parts thereof in section. Fig. 2 is a plan view of the ear or hanger and Fig. 3 is a perspective view of the spring which forms a detachable part of the ear. Fig. 4 is a vertical cross section on line H of Fig. 1, find Fig. 5 a similar section on line 55 of The invention comprises a trolley car body 2 of elongated shape and form which is channeled longitudinally at its bottom, as usual, to clamp and hold a trolley wire 3. Body 2 includes round and flattened vertical enlargements 4-4 at or near its opposite extremities which terminate in short round stubs or projections 5--5 having transverse openings 6 a short distance above the fiat annular seats or shoulders 7 at the base of said projections. A longitudinal reenforcing web 8 extends between the two spaced enlargements or bosses 4-4; and this web 8 is of less height at the middle of the body than at said bosses to providefree play for a flat spring strip 9 which rests at its opposite ends upon the flat tops or seats 7 of the bosses 44:. The opposite ends of spring 9 are provided with elongated slots or oval openings 10 to permit these ends to be sleeved over the round stubs 5-5 and to be fastened thereto by means of flat round washers 11 and cotter pins 12. The width of the slots or openings 10 are substantially the same as the diameter of the stub 5 projecting therethrough to prevent lateral movement of the body and spring relatively to each other. On the other hand the elongated opening 10 allows sufiioient longitudi nal play of the spring relative to the studs so that the spring may flex within limits upwardly and downwardly in respect to the ear or body 2 whenever a trolley passes underneath the same, it being understood that the device as a whole is suspended at the middle of the spring by a yoke member 14 having a screw-threaded opening 15 in its upper portion adapted to} permit a screw connection to be made with an insulator 16 or other supporting part substantially as shown in dotted lines in Fig. 1. The top of member 14.- is preferably provided with locking serrations 17, and the bottom portion is preferably in the form of a wide flat loop 18 having a central rivet opening extending into the bottom of the screw-threaded opening 15 to permit the use of rivet 19 in fastening the spring immovably in position within this yoke member. The loop itself envelope the spring and carries the load and the rivet prevents the spring from shifting longitudinally. The central position of the supporting yoke upon the strong flat steel spring permits body 2 to rock and accommodate itself to the varying deflection of the trolley wire before the trolley actu ally reaches the hanger, and the spring also yields under the upward pressure of the trolley when the trolley passes directly underneath the hanger, thereby relieving the rigid places of union in the supporting structure of bending and twisting strains.

What I claim, is-

1. A trolley-wire hanger, comprising an elongated body having trolley wire gripping means at its bottom and a pair of spaced projections at its top, and a flat spring detachably connected with said projections havin a supporting member at its middle.

2. 1 trolley-wire hanger, comprising an elongated body having a pair of spaced projections provided with transverse openings, and a fiat spring loosely and detachably connected with said projections having a supporting member aflixed centrally thereto and fastening devices for said spring removably secured within said transverse openings.

3. A trolley-wire hanger, comprising an elongated body having vertical projections at opposite ends thereof, a flat spring detaohably engaged at its opposite ends with said projections, and washers and pins adapted to secure said spring to said projections,

4. A trolley-wire hanger, comprising an elongated trolley Wire supporting body having vertical projections at its opposite ends, a flat spring having elongated openings at its oppositeends adapted to receive said projections and provided at its center with a supporting member, and means adapted to detachably fasten the ends of said springs to said'projections.

5. A trolley-Wire hanger, comprising a trolleywire gripping body having a fiat spring afiixed loosely at its opposite ends to the upper side of said body, and a supporting yoke riveted to the middle and upper side of said sprin In testimony whereof f aflix my signature.

JAMES SCOTT.
